Swine flu loses, Boston Latin kids sing

Don't you hate it when you're supposed to sing at the Pops but that swine flu gets in the way? That's the case with a group of Boston Latin students who were supposed to get some stage time on May 20 but had to cancel because of the swine flu fears. They're at Symphony Hall tonight as winners of the Fidelity FutureStage music competition. We'll name them. Chris Middleton, 17, is a pianist and singer who will play an original ballad backed by the Pops. Then the Grieg Quartet - B. Kim, 15, on violin; Tadesh Inagaki, 17, violin; Allyn Hayes McCourt, 17, violin; Christopher Nguyen, 17, cello - perform Grieg’s String Quartet No. 1 in G Minor.
